ABSTRACT:
The present invention provides a roofing fastener, a roofing assembly including the roofing fastener, and a method of installing the roofing fastener into the roofing assembly. The roofing fastener includes a head and a shank integrally connected thereto. The shank and the thread thereon permits the roofing fastener to be self-tapping and threaded into a base substrate such as a concrete deck. Preferably, the roofing fastener includes a polygonal socket within nubbins thereon to squeeze about a drill bit. Also, ideally the head of the roofing fastener is round and has a diameter which is greater than the length of the shank. Ideally, the fastener is made of a low-moisture material which can absorb water from the surrounding substrate causing the fastener to swell and increase its holding power.
